Hi, I am dr. Sreepriya. Paediatrician
You are concerned that child is not consuming milk well for past 2 month
If your child is active, playful,not crying more and weight gain is good there is no need to worry
Added to that child should pass urine and motion normally
I feel, Probably child has become more playful and is not drinking
Next Steps
Start semi solid food after completion of 6 months only
You can start with ragi first
The rice with curd, dhal, vegetables
Fruits, fruit juice also can be introduced after 6 months
Remember don't introduce every thing together
Slowly one by one food items can be added
Continue your breast milk till 2 years of age
